You all are compleatly not even following what im saying! I am not telling him to run HOT ENGIN bay temp sheez. Jumping to say to no no dont even do it jus dont do it. Well all that looks like is you know ur wrong and dont want him to see it for himself. moving the afm somewhere dosent matter. What I told him to do is take a pipe and your afm and filter as short as you posibly can make it and and hook it up to your TB. Yes this is hot air this is for testing purpose!!!! so he can have a feel of what a longer and shorter length will efect and he can post his results. After that he can decide what he likes more and there devise another plan to get cold air if desired. perhaps a hood scoop runing right in that would be cold air! Next time read my post first.
muythaibxr I think you have a point there but the low end torque suffers b/c of the length requires much more VAC from the motor to pull in resulting in lag.
As NZ said a smaller pipe will just add PSI of flow IE exhoust. But he compleatly forgot to relize that a NA engin has no posible way to create PSI untill combushtion chamber is reached thus the rest of the car performs in a atmospheric presure du to only being VAC fed.
kontakt Your first peragraph said volum of air a problem. I dont see it as a problem it just creates a diffe power curve as a short one. Your last peragraph if I understand your post correctly is right along the lines of what I have ben saying.

my first paragraph commented on what you'd said at one point that i don't feel like finding about if you had a 6" wide section of pipe it would cause a lag, i was saying that i believe that to be untrue. Also I wasn't saying the volume of air was a problem, but that the resistance to movement that you claimed it created wasn't a problem. However i was agreeing with you in some ways. The next part would read better as "Lenght of pipe determines flow in another manner as well" I also meant to point out the tumbling effect of the air in a longer pipe using the same illustration, but was at work at the time, and a little distracted. I agree with a fairly short intake route, but i also agree that it must be cold. The CAI that I put on my Legacy rams cold outside air into the intake via. the right fog light hole, the intake was made overall shorter, and no longer drew air from the engine bay, and I have been happy with it so far, but different things work on different cars. One other thing that I should note is that the EJ series of engines (impreza/legacy) are very particular about their intakes. Because of this (and having owned one) a lot of my relearch on CAIs has involved their peculiarities, but it might not be a bad idea to read up on what goes wrong with them, because potential problems will probably be more well documented than with other cars. ohh, and... ya know, buy a dictionary too

Edit: note, unless the size of the piping restricts flow, a narrower pipe will flow faster for the same volume, and speed of incoming air is important on a rotary to help fill the compustion chamber better at low RPMs (ever hear of a velocity stack?)

With replys like that you may want to go back to the play ground and take some more lessons.

I am baffled with your wisdom. Plz help me show me facts oh wise one.
Allmost evryone of you retaliate like midle schoolers and bring nuthing to the plate. I have to say its good for a laugh but sad for argument sake. Is that the best you can do is bitch about grammer sheez thats pathetic. I thought you were sapost to debate 13b's here guess I went to wrong room.
RX7havic may be able to shed some light b/c to me no one but nz in argument sake has givin a shred of inteligance towrds his issue am I wrong rx7havic? So know how in thread seems to = 4 maybe and ignorance 12 or so. Hmm midle school all over again.

I have no problem admitting you are wrong, so I'll just say it. You're wrong. There... I admitted it.

This thread is quite amusing!
I like the "PSI of flow" concept, that one is new to me. I think I'll start measuring my own weight in gallons. Thanks for the inspiration, iceblue!

If the afm is positioned wrong you can experience problems, either too much fuel or less fuel. I have personally experienced this, with those results... So that responce you made about the afm is totally ignorent....

Nz...As NZ said a smaller pipe will just add PSI of flow....<--that ends Nz quote from earlier after that I was adding my own imput.
Martin. Ok I take that back if you place the AFM verticaly where grafity is pullin down on the door it could run to rich from improper spring tenshion.

I just wanted to point out that nothing iceblue has said has made sense, and if he was so powerfully educated regarding fluid dynamics and things of that nature, he'd more than likely have picked up some understanding of how to communicate his thoughts and ideas into writing.

Good grief, you guys are unreal! This whole thing started with me noticing a diff curve in my acceleration get-up...
~With true CAI installed I notice a slight lag around low end, but faster get-up at high end.
~With stock installed the lag disappears, but high end loses it's get-up.
My AFM is positioned correctly with the CAI. I have yet to run it with the AFM being closer, but I will try that when I get a chance, just to see what it feels like for test purposes only.

Not much to a CAI setup...pretty cut & dry.
I'll play around with it. AFM is sitting nearly close to stock position and vac lines are hooked up correctly. What more can there be? Keep in mind....I said Slight lag.

I sorry NZ the quote on PSI was posted by martin.
No The other half of the car befor the exhoust is capable of flowing bettor then the exhoust thats why opening one part increses power.
Wrong again. Yes the AFM mesures air passing through it but if you stick a 1in pipe on it you will be incapable of flowing the maximum amount of air through it or as much air as a 3in pipe.
Theory stand ^

But we know that is not how it works. Put a bigger exhaust on a car and it will make more power despite the fact that the same airbox is there. Change the airbox for a pod filter and the engine makes more power despite the ports being untouched. The smallest part of a system does not make the system flow as if it were all that size. Forget that idea now.
